Uniparental disomy (UPD) is the inheritance of both homologous chromosomes from a single parent. Most chromosomes involving UPD have no pathogenic effects. However, abnormal phenotypes in cases with UPD can be mainly caused by disrupting genetic imprinting and by uncovering harmful autosomal recessive mutations. The documented phenotypes of UPD associated with imprinted genes include maternal UPD for chromosomes...
